You'll likely need to build a script to produce the correct found set. If you want to do this using a button from your data entry layout, you can use a handy script step called Go to Related Record. This tells FileMaker to find all the records that are related to the current record. The script might look something like this:

If [ not IsEmpty ( EventsItems::ItemNo ) ]

Go to Related Record [ Current Record ; Layout: Quote ]

Sort [ {sort order you specify} ]

Page Setup [ Restore ]

Print [ Restore ]

Go to Layout [ EventDetails ]

End If

You can play with the different options on the various script steps to tailor this to do exactly what you like, but that's the general idea.
